Application tiled March 5, 1810. Serial No. 547,460.

T0 all whom it may concern Be it known that I, ALFRED B. WALES, a citizenlof the United States, residing at IVhitman, in the county of Plymouth and State. of Massachusetts, have invented an Improvement in Buttonhole Spacers and l\flarkers for Buttonhole-Machines, of which the following description,l in connection with the accompanying drawings, is a specification, like letters on the drawings representinglike parts.

This invention relates to the spacing of button-holes and particularly to a buttonhole Spacer and marker for a button-hole machine.

The cutting and stitching or sewing of button-holes, and especially such a formation of button-holes in such Work as "shoes, requires an accurate spacing of each hole with regard to the hole .1astmade. It is, moreover, desirable that such spacing be marked so as to be visible to the operator of the machine, while preferably such mark should not be of such permanent nature as to deface the Work. It is, furthermore, desired that such a spacer and marker be applicable to any button-hole machine Without reorganizatlon of the machine or the attachment, or of the cutting and sewing or stitchi ing mechanisms ordevices.

To the end, therefore, of providing aspacing and marking mechanism which shall be capable of performing these: desired functions and at the same time have the necessary characteristics of adaptability to various machines, I have devised my present inL vention, which, broadlystated, comprises the combination with a` buttonhole making machine, including buttonhole cutting mechanism and buttonhole stitching mechanism, of means automatically operated once only during each complete cycle of operations of the machine to mark the workfor the next succeeding buttonhole at a predetermined distance from the buttonhole being made so that the markl thus produced may be utilized in locating the work accurately for the making of such neXt succeeding buttonhole.

In the specific embodiment of the invention about to be described, I have provided for the adjustment of a marker with relation to the point of operation of the ma- A chine and for vthe gaging of such adjustwardly into forcible marking engagement. with the Work invariably at the same dis-l tance from the lpreceding buttonhole once for each button-hole,'so -that when the work is moved along' the mark thus made on the Work Will indicate the correct position for the next button-hole each time the Work is moved. e

The structure and operation'of my device will be more fully described in thespecication which follows and it is illustrated in the drawings which form a part-of that specification. In these drawings I have shown as an illustrative embodiment of my invention a combined spacer and marker adapted to be attached to a button-hole machine of a standard type, and this embodiment I have described in .the specification, reference being made to corresponding parts by the use of reference numerals similarly applied throughout.

Inthe drawings :-Figure 1 is a side view partly in. section of the portion Vof a buttonhole machine equipped with a spacer and marker, in accordance `With my invention, F ig. 2 is an enlarged plan view of the same with the upper portion 'of the machine broken away, Fig. 3 is a detail in plan' 0f the marker arm and adjusting lever, Fig. 4 isa sectional detail of the presser foot viewed from a direction' opposite-tothat of Fig. 1, and Fig. 5 is a sectional detail on the line 5--5, Fig. 2.

1 is the overhanging head, 2 the bed and 3 the base of a button-hole machine.

4 is a needle carried,operated and guided in any usual manner.

5 is a button-hole cutter or knife carried on an arm 6 lWhich is rocked and timed in any suitable manner to cut the button-holes which are to be stitched.

7 and -8 are a pair of oppositely faced (presser feet.

10 between the ears of a block` 11 which is screwed to the bed 2l of the machine. The lower end of jthe arm 9' is carried down and terminates ina return hook 9 which is engaged by an oppositely faced hook 11x (see lFig. 1.) rlihe hook l1c is raised and lowered by a toggle l2 which is pivoted at its upper end 13 tothe bed of the machine and at its lower end 14-` to a bar 15 connected to the hook 11". 1

16 is a hand lever engaging at 'it's lower end 16. the center pivot of the toggle 12.-

With 'the lever in the position shown. in Fig. 1 the toggle 12 is in its collapsed position. By drawing the lever 16 toward the .v

20 is aplate having an extension 21 upon -which a clamping strip 22 is held( by the screws 23. 'By adjustingthe screws 23 the arm 9 of the, presser foot 7 may be clamped between the extension 21 and the stripy 22.

yThis permits `the adjustment of the spacer and marker of which the plate 20 is a part upon the arm of the presser foot. On the under side of the plate 20, adjacent the part 22, is pivoted an arm .24 through the for-v ward end-of which is set a pointed screw 25.

The point ofi the screw 25 constitutes a marker which will make an impression 'on the surface of the leather, or other upper material; suiicient to be discernible. rl`his impression, however, will subsequently disappear but will remain visible long enough for theoperator to use it in properly positioning the work under the knife and needle,

The arm 24 is continued beyond its pivot at 26 so that it is in the form cfa bent lever or bell crank.` On the end of the extension 26 is a segmental gear 27 with which meshes a pinion 28 formed on the end of a lever 29. The lever 29 is pivoted central-ly of the plate 20 on a stud 30 upon the upper end of which is a thumb nut 31 which may bev loosened to move or replace a gage disk 32.

33, 34 and 35 are a plurality of scales of increasing size in graduation. These, for instance, would'be respectively for. childrens, womens and mens size shoes. Y

The disk 32 is provided with perforations 36 of a number corresponding to that of the scales, that is in .the present case there would be three perforations These perforations'are adapted to be engaged by. a pin 3'( so that any one of the dierent scales which may be desired may be moved into the arc of play or iield of the indicator or pointer 38 which is set on the lever29 so as to overlap the margin of the plate 20 -was made from the first button-hole.

matinee' and travel with its point in close proximity to the margin of the disk32 and of that the presser foot 7 is raised it will be clear ofthe work beneath it but when the presser foot 7 is downit will be in marking contact with the. material of the upper, it will be evident that each time the presserfoot is moved down into clamping pos1t1on, the

point of the s'crew 25 will be pressed hard against the top surface of the work so as to make a preferably dull butv clearly visible and well defined mark on the work. inasfmuchas this downward marking movement ofthe marker is caused automatically by a part,` viz. the presser f oot, which moves up `and' down invariably 1n the same position with relation tov the button-hole making mechanism,for instancey with reference to the knife 5, it follows that the marker will accurately' space the work, keeping yjust one mark ahead of the actualbutton-ho'les all the 'time'. As the work is moved into position to have 'a button-hole made in it, and is clamped by the' presser foot, the marker 25 is thereby automatically brought down upon the work in marking position, with the result that a mark is impressed on the work at a distance from the'button-hole corresponding to the distance between the knife 5 and the screw 25. Vihen the button-hole is nished and the work is moved along so as to bring the mark which has been thus made on ythe work into accurate position beneath the knife 5 and is then clamped, said clamping movement causes the marker automatically to make another mark at exactly the same distance from the point at which this second button-hole will be made that the firsty mark rlihis marking is repeated, the spacing being always accurate and exactly the same, without any further attention from the operator, because the downward movement of the presser foot causes the marker each time to mark in its place, and as the presser foot has no lateral movement but always goes up and down 'in exactly the same path, it follows that the marker 25 necessarily marks invariably at the same distance from the knife 5 and hence spaces the button-holes with the utmost aclcuracy. lf a' different spacing is desired, the

arm 24 is swung to the right or left as required, by the manual adjusting means. The disk 32 should preliminarily be turned so as to bring the scale which corresponds to the class-of work to be operatedupon in position to coperate with the indicator 38. lin the instance shown in F ig. 2, the scale of'smailest graduations is shown so positioned. The

lever 29 is then' moved until the' indicator 3 points to the graduation WhichA shows the particular size of shoe which is to be buttonholed. In the instance shown 1n Fig. 2 this is eleven. The movement of the lever 29 rooperation'of my device but these are undered to and operated by the said moving part' stood to be included Within the spirit of my invention if Within the limits of the appended claims. v
